Adds ssautil.Packages function, which creates ssa.Packages
from packages.Packages.
Deprecates testmain synthesis logic now that go/packages
reports the test packages synthesized by the build system
as first-class packages.
Updates docs, examples, and tests.
Flags potential confusion around legacy concept of "importable" packages.

Also:
- extend Parent() to all Values and add to interface:
(Builtin/Const/Global => nil; Function => Enclosing)
- hide Function.Enclosing since it's now redundant wrt Parent()
- make (*Function).String robust for synthetics without pkg object

Method Signatures (types.Signatures with a non-nil receiver) behave
like ordinary func Signatures in the hash function/equivalence relation
used by typemap.M, which leads to surprising incomplete traversal
over the type graph if an M is used to remember types already
visited.
This change avoids ever putting method Signatures in a typemap.
% go test -v code.google.com/p/go.tools/go/ssa
now repeatedly shows the exact same number of functions and
instructions.
(We should discuss how to avoid this problem more generally.)
Also:
- recur over the params/results of all the methods of
each type when computing necessary method sets.
- there's no longer any need to treat declarations of unexported
methods as a root for traversal. Added test case.
- enable SourceImports flag in stdlib_test, which was dropped
during a recent refactoring (d'oh).
- doc tweaks
